iis-6 - 在 Win2008 R2 上禁用 TLS 1.0 会破坏我们的 IIS 网站

Question

我们正在运行 Windows Server 2008 R2。 TLS 1.0 不符合 PCI 标准已经有一段时间了，通过 Windows 注册表禁用它很容易。但在过去，禁用 TLS 1.0 给我们带来了 2 个问题:

1. 无法通过远程桌面连接到服务器。
2. 我们的 IIS 6.1 网站不​​可用。

问题 #1 已通过 MS 补丁 KB3080079 修复，但一旦 TLS 1.0 被禁用，我们的网站仍然会离线。禁用 TLS 1.0 时，我需要做什么才能保持 IIS 正常运行以及网站在线？

以下是错误消息，仅当在注册表中禁用 TLS 1.0 且服务器重新启动后才会出现该错误消息:

注意:TLS 1.1 和 1.2 已在注册表中手动启用。

我想我已经发现，当 TLS 1.0 被禁用时，SQL Server 实际上是问题的原因。 (这会导致我们所有的网站崩溃。)对此有一个修复:https://support.microsoft.com/en-us/kb/3135244
